Recently, Chinese scientists have achieved breakthroughs in the search for antimatter research. Scientific researchers from the Institute of Modern Physics of the Chinese Academy of Sciences and other institutions found an antimatter named "anti superhydro-4" by participating in an international cooperative experimental study, which is the heaviest antimatter hypernucleus observed by scientists in experiments at present. This discovery has taken an important step forward in the exploration of antimatter and the symmetry between antimatter and antimatter, and will also have a driving effect on unraveling the mystery of the early Big Bang in the future. The relevant research results were published in the international academic journal Nature on August 21st Beijing time. What are normal matter and antimatter? Current physics knowledge suggests that at the beginning of the birth of the universe, there should have been both positive matter and antimatter, and that they existed in equal quantities. But now it is difficult to find antimatter in the universe, so many people are curious, where has antimatter gone? The answer given by scientists is that antimatter can easily annihilate with surrounding positive matter, meaning it exists and disappears. If the amount of positive and negative matter in the universe remains equal, they will eventually completely annihilate and turn into a ball of light. Fortunately, under the influence of some physical mechanism, there is a quantitative imbalance between positive and negative matter. A portion of the excess positive matter was not annihilated by antimatter, forming today's world and the foundation for the birth and existence of human civilization. In this case, scientists are eager to find antimatter in some way, in order to uncover a series of mysteries such as the beginning of the universe in the laboratory.
